Mozark, a digital experience testing and measurement company, has raised $40 million in a Series B funding round led by International Finance Corporation and RMB Capitalworks, with participation from existing investor Kalaari Capital. The company said the funds will be used to accelerate global expansion and pursue strategic acquisitions.
Mozark develops technology that measures the real-world performance of digital services across devices, networks and geographies without collecting user data. Its AI-assisted platform simulates user journeys across applications, networks and infrastructure, enabling organisations to detect and address performance issues before they affect customers.
The Series B funding will support the company’s next phase of growth, including expanding its real-world testing and measurement capabilities across the digital AI stack. This includes applications, networks and AI infrastructure, with the aim of improving reliability and consistency in digital experiences. The company also plans to expand its presence in key markets such as the United States and countries across the Global South.
“AI is accelerating digital services everywhere, but experience quality remains disparate and unreliable and that directly impacts the broader digital divide,” said Kartik Raja and Fabien Renaudineau, founders and co-chief executives of Mozark. “Mozark enables organisations to measure and improve service performance in real-world conditions, detect gaps early and ensure reliable digital experiences at scale.”
Founded in 2019 by Chandrasekar Ramamoorthy, Kartik Raja and Fabien Renaudineau, Mozark works with enterprises, telecom operators, regulators and public-sector organisations to conduct large-scale digital experience testing. By executing scripted user journeys on real devices across real networks and locations, the platform generates synthetic experience telemetry that helps organisations identify performance gaps across the AI-native technology stack.
“With this funding, we will accelerate commercialisation of our agent-to-agent communication testing platform, which will underpin the next generation of digital interaction,” said Chandra Ramamoorthy, founder and chief product officer of Mozark.
The company currently serves more than 50 enterprise and government clients across over 20 countries, including telecom operators, financial institutions, regulators and global digital-native organisations. Its deployments run simultaneously across several thousand live devices and have already executed more than 25 million tests supporting benchmarking and user-experience assurance analytics at scale.
Investors said the funding would help strengthen global digital infrastructure and expand access to reliable digital services. “Our investment in Mozark will support innovation, skilled job creation and broader access to digital services,” said Farid Fezoua, director for Equity, Funds and Venture Capital at International Finance Corporation – World Bank Group.
Robert Oudhof, director at RMB Capitalworks, added that the investment will enable Mozark to expand its enterprise customer base globally, build long-term partnerships and continue investing in advanced research and development to maintain its technological edge.
